Simple Harmonic Motion
Which expression represents the period (T) of a mass-spring system in simple harmonic motion?
If a simple pendulum's length is quadrupled, by what factor does the period of its oscillation change, assuming small-angle approximations remain valid?
The period remains unchanged.
The period increases by a factor of 4.
The period doubles and then quadruples.
The period increases by a factor of 2.
How does increasing the mass of an object on a spring affect the period of oscillation for that spring-mass system?
The period decreases.
The period increases.
The period remains unchanged.
There is not enough information to determine the effect on period.
Which of the following will period NOT depend on in either mass-spring systems or pendulums?
gravitational field
mass
amplitude
spring stiffness or constant
True or False: "For a simple pendulum, the period increases with the length of the pendulum and decreases with the magnitude of the gravitational field."
Cannot be determined
Sometimes
true
false
In a pendulum swinging back and forth without friction, what type of energy transformation occurs as it reaches its highest point?
Kinetic to gravitational potential
Chemical to gravitational potential
Thermal to kinetic
Gravitational potential to thermal
In an experimental setup where two identical springs are arranged in parallel attached to one block oscillating horizontally, how does this arrangement compare to one spring with half its original stiffness?
The parallel springs result in half the period compared to one less stiff spring.
The parallel springs result in four times shorter period than one less stiff spring's period.
The parallel springs have twice the period compared to one less stiff spring.
They have equivalent periods for oscillation.

What occurs when an external force acting upon an oscillator matches its natural frequency?
There's negligible change given that external forces don't typically influence oscillators' intrinsic characteristics significantly enough for noticeable impact.
Oscillation periods are substantially shortened since external force applications enhance system dynamics propelling faster cycles consequentially.
Resonance takes place, resulting in dramatically increased oscillation amplitudes.
The oscillator rapidly comes to rest due to destructive interference effects occasioned by the external force application.
Which variable when altered changes both maximum velocity and kinetic energy amplitude of oscillation for a symmetrical spring-mass system?
The spring stiffness constant (k).
The gravitational acceleration (g).
The mass (m) attached to the spring.
The elongation from equilibrium position (x).
What instrument is commonly used to measure the period of a pendulum in a physics lab?
Thermometer
Stopwatch
Ruler
Caliper
